Incoming and Outgoing mails not working

Incoming and Outgoing mails not working

Hi,

I added my domain to zoho mail, and verified it and changed the MX record on DigitalOcean, Then created new user info@garvi.lk
But I can't send or receive any mails, and there is no error responding to info@garvi.lk

Is there any other thing to do in my control panel?

Thanks.
